Question 1138158: The sum of the ages of Roberto and Guadalupe is 88 years. 6 years ago, Roberto's age was 3 times Guadalupe's age. How old is Roberto now? Answer by VFBundy(438) (Show Source):
You can put this solution on YOUR website! Roberto's age now = x
Guadalupe's age now = 88 - x
"6 years ago, Roberto's age was 3 times Guadalupe's age":
x - 6 = 3(88 - x - 6)
x - 6 = 3(82 - x)
x - 6 = 246 - 3x
4x = 252
x = 63 Roberto's age now = x = 63
Double-check:
Roberto's age now = x = 63
Guadalupe's age now = 88 - x = 25
"The sum of the ages of Roberto and Guadalupe is 88 years":
63 + 25 = 88
"6 years ago, Roberto's age was 3 times Guadalupe's age":
63 - 6 = 3(25 - 6)
57 = 3(19)
